Best Mods That Overhaul Diamond City in 2025

Summary

Fallout 4’s Diamond City was a great concept, but players always felt like there should’ve been more to it.
Using just a few mods, Diamond City can be totally overhauled to the sprawling, wasteland city it was supposed to be.
Filling in the whole stadium with new structures and details, NPC’s and quests and NPC’s, even new custom weapons and armors to use.

Known as the “Great Green Jewel” of the Commonwealth, Diamond City is the large center hub of Fallout 4’s map. Founded around 2130 in the ruins of Boston’s Fenway Park, the Commonwealth’s largest settlement was constructed as a peaceful city for those seeking shelter from the dangers of the wasteland.

While it’s an interesting location, the truth is that this central attraction of the Commonwealth always needed a bit more love. Thankfully, the modding community has put in the work over the years, developing tons of mods to overhaul the location, from expansions to the city’s layout and structures, to full-on new quest lines to play through. When used together, this batch of mods takes the old, dilapidated baseball stadium, and turns it into the true, post-great-war city it’s supposed to be, in all its radioactive glory.

Diamond City Expansion + eXoPatch

Diamond City, But Expanded! (And Fixed)

Diamond City Expansion is a staple when it comes to location overhaul mods for the city, not just for how popular it is, but also for how much content it offers. Tons of new structures have been added to the usually empty upper and lower stands that surround the city’s main area, with some work done to some interior areas as well. This makes the city feel more alive and populated, gives it much more detail, and makes it seem like the sprawling wasteland metropolis it was meant to be.

Fallout 4 Mod Adds Popular Feature From New Vegas

A popular Fallout 4 modder brings one of Fallout New Vegas’ best features to the game, and the Minutemen will never be the same.

While the mod’s original author is no longer working on the project, a user by the name of Exoclyps has created their eXoPatch Mod. This project takes the original Diamond City Expansion mod and fixes some small bugs it had left over, while also making some changes to improve performance and compatibility with other mods. It’s pretty much a requirement for any player looking to use the older Diamond City Expansion mod.

The Fens Sheriff’s Department – Bleachers 2

A Massive Quest Mod Filled With Content

The Fens Sheriff’s Department – Bleachers 2 was one of 2023’s biggest mods for Fallout 4. It won February’s Mod of the Month on Nexusmods that same year, much like the first Bleachers mod did in 2021. It adds a bunch of new content, from quests and locations, to NPCs, equipment, and items, all custom-made to fit in with the game’s aesthetic.

Fallout 4 Mod Adds New Faction, Quests, and Nearly 18,000 Voice Lines

A new Fallout 4 mod releases online, featuring a wide range of features that gives a new lease of life to Bethesda’s classic RPG.

The mod’s content is mostly situated within Diamond City, adding in a new layer of depth by expanding the bleachers area with new buildings and details. Its questline is also a blast to playthrough. Not to mention it includes a handful of brand-new, fully-voiced NPCs to break up the common, reused voices similar to other Bethesda Games. All the content it brings adds much-needed diversity and style to the city overall.

Diamond City Outskirts

A Much-Needed Exterior Revamp For The City

While Diamond City is mostly contained within the stadium itself, the surrounding area still provides its own uses, especially for its defenses. That’s where Diamond City Outskirts comes into play, bringing a much-needed upgrade to the settlement’s outer areas.

The mod’s author, SGTMikey, went about bringing more offerings to the city’s outer area, adding a totally new area with passageways running through the stadium’s walls. The various hallways range from small markets with unique, custom vendors, to abandoned and eerie corridors. It fleshes out the usually mundane exterior of the Green Jewel in its own creative way, while still fitting perfectly with the Fallout theme. It could easily seem like a part of the base game itself.

Diamond City Guards Redux

Diversifies Diamond City’s Security

The settlement’s guard force, Diamond City Security, did have a unique design in Fallout 4, with their style being heavily inspired by classic baseball attire. The problem was the lack of variation. Every guard looked like a copy of the next, making them all feel sort of like robots. (Who knows, maybe they actually are synths.)

But Mortercotic has gone about fixing this with their project, Diamond City Guards Redux. This mod gives the city’s security force a much-needed revamp. It gives them a larger pool of possible weapon and armor combinations they can spawn with, as well as buffing their stats overall to make them much more of a force to be reckoned with. It does a surprising amount for the city by making just a few changes to one of its most common NPCs, and gives the population of the Great Green Jewel even more diversity.

Diamond City Vendor Clutter

Because Vendors Should Display Their Wares

The merchants of Diamond City are an interesting bunch, like Soloman with his selection of definitely-legal chems, or Moe and his lineup of “swatters.” There’s Takahashi, the city’s robotic chef with a specialty in noodles. These characters are great on their own, each unique in their own way, but the same can’t be said for their mundane storefronts.

Fallout 4 Player Notices Hidden Diamond City Store Detail After Nine Years

A Fallout 4 player online notices a hidden detail about one of Diamond City’s stores, nine years after the game first launched.

Despite their inventories being full of anything a wastelander could ever need, their market stalls are merely dotted with a handful of items. Luckily, modder creodron has seen to fix this by loading the various market stalls with a selection of equipment and items representative of each shop’s inventory. While it’s only a small change in concept, it adds that extra layer of detail to make the city feel more lived-in. More importantly, it adds more immersion, a highly coveted factor in the modding community.

Optimization and Compatibility for Diamond City

Makes It All Work In Harmony!

It’s easy to see how these few mods can transform Fallout 4’s Diamond City into something completely new for the game. Alas, there’s always one big question when it comes to modding: are they all compatible?

While these mods each do different things in and around the city, with the way modding works in Fallout 4, there is bound to be overlap somewhere in the various records they edit. Thankfully, mith077 has created a mod that’s essentially a mega patch that lets all of these mods (and even more) work together without problems. Better yet, the installation itself is modular, so players can pick and choose which mods they are using so the correct compatibility patches are added. In culmination, these few mods take the old Diamond City and turn it into a settlement truly worthy of its title as the Great Green Jewel of the Commonwealth.
